PATENT OFFICE Application March 9, 1936,v serial No'. 67,984 In Canada May 31, 1935 1 Claim.

The invention relates to a burner construction and more especially to a gas burner.

The primary object of the invention is the provision of a burner, wherein burner oriilces are readily and easily accessible so that the same can be conveniently cleaned should they become corroded and without removal of a burner from a furnace, the llame tubes of the burner being of a construction to direct the llame to the walls of l0 the furnace and thereby eliminating the employment of a deflector for the spreading of the llames.

Another object of the invention is the provision of a burner of this character, wherein the parts are of such construction as to assure easy assembly and maintaining a low cost of production and such burner is covered in a manner to shut off the unnecessary air from the center of the furnace and diverting the air to a gas flame, the burner in its entirety being of novel construction and is of the Bunsen principle.

A further object of the invention is the provision of a burner of this character, which is extremely simple in construction, thoroughly reliable and eillcient in its operation, durable, readily and easily installed within a furnace and inexpensive to manufacture.

With these and other objects in View, the invention consists in the features of construction, combination and arrangement of parts as will be hereinafter more fully described, illustrated in the accompanying drawing, which discloses the preferred embodiment of the invention and pointed out in the claim hereunto appended.

In the accompanying drawing:

Figure l is a fragmentary elevation of a burner constructed in accordance with the invention.

Figure 2 is a sectional view on the line 2--2 of Figure l looking in the direction of the arrows.

Figure 3 is a top plan View.

Figure 4 is an enlarged sectional View on the line lI- of Figure 1 looking in the direction of the arrows.

Similar reference characters indicate corresponding parts throughout the several views in the drawing.

Referring to the drawing in detail, the burner comprises, in this instance, a pair of upper and lower half circular shaped brackets I0 and II, respectively, these being disposed in their superposed spaced relation in a horizontal plane and the upper brackets III, each has an upstanding flange I2 at its outer marginal edge.

Removably iltted with these brackets I0 and I I are the vertical portions of flame tubes I3, these being spaced perpendicularly uniformly from each other and each has a contracted lower end I4 accommodated in a correspondingly sized opening in the lower bracket II, the contracted end being for the formation of a seating shoul- 5 der I5 for the tube so that it will rest upon the lower bracket II when in working position. The tubes I3 have the upper laterally angled burner tips I6 for directing the flame against or toward the wall of a furnace accommodating the burner. 10

Tie rods Il join the brackets I0 and II in their superposed relation to each other to provide a unitary supporting frame for the flame tubes.

Beneath each lower bracket Il is a. gas fuel supply pipe I8, it conforming to the shape of said 15 bracket I I and at its front is joined by a coupling I9 with a source of fuel supply while the rearmcst end of such pipe is suitably plugged for the closing thereof. This pipe I8 at its upper side has formed therein burner oriilces 2D, these confront- 20 ing the lower open ends of the flame tubes I3 for the jetting of fuel into said tubes.

Removably resting on the upper brackets I0 is a 5 plate 2| which shuts oil the center air within the furnace and thus closing off the unnecessary air 25 from the center of said furnace and diverting the air to the gas flames. The pipe I8 is uniformly spaced below open lower ends of the flame tubes I3 so as to allow air to follow the jet for proper mixture of air with the fuel for perfect combustion in the operation of the burner, the spacing of the pipe I8 from the lower bracket I I being had by the leg 22 depending from the lower bracket and seated upon said pipe. The tips I6 of the flame tubes rest in notches 24 in the upstanding flanges I2 of the brackets I0 so that the turning of the flame tubes from their set position when iltting the brackets will be avoided, the tips being extended beyond the flanges I2 for considerable spread of the burner when lighted. These brackets I0 and II are held uniformly spaced from each other through the medium of suitable sleeves 23 which surround the rods I'I and constitute the spacers for the said brackets I0 and II and the latter are held ina rigid position while the llame tubes I3 are readily removable from these brackets for cleaning by sliding each tube I3 out from the brackets I0 and I I without removal of the brackets or burner from the furnace. The supply pipe I8 with the perforations 20 in the upper side thereof has those rods I'I at the extreme ends of the brackets I0 and II, each passed downwardly through the leg 22 next thereto with the lower end of such rod I'I threaded into the supply pipe I8 so that these parts will be joined in this manner although such parts can be otherwise joined.

By the arrangement of the burner and its construction a deflector is unnecessary for the spreading of the flames when the burner is operated because the tips I6 direct the flames from the tubes I3 straight to the walls of the furnace.

What is claimed is:

A gas burner comprising vertically spaced horizontally arranged substantially half ring-like brackets having vertically aligned openings, flame tubes removably fitting said openings and having laterally angled upper ends and reduced lower ends forming shoulders seated against the lowermost brackets concentrically of the openings therein, means holding the brackets in spaced relation to each other, a fuel pipe beneath the lowermost brackets and spaced from the lower ends of said flame tubes and having burner orifices opening upwardly in the direction of said ame tubes, upstanding flanges at the outer peripheral edges of the uppermost brackets and having rounded notches forming seats for the laterally angled upper ends of the flame tubes, the said angled upper ends of the tubes being `extended beyond the anges and forming tips, a disk-like plate removably seated on the upper brackets with the tips concentrcally thereabout, and fasteners included in said means for detachably holding the fuel pipe in xed position.
